Number of elements in enumeration type
output = H5T.get_nmembers(type_id)
output = H5T.get_nmembers(type_id) retrieves
the number of fields in a compound data type or the number of members
of an enumeration data type. type_id is a data
type identifier.
Determine the number of fields in a compound dataset.
fid = H5F.open('example.h5'); dset_id = H5D.open(fid,'/g3/compound'); dtype_id = H5D.get_type(dset_id); nmembers = H5T.get_nmembers(dtype_id);
